Telepointing issues in desktop conferencing systems

Abstract

In WYSIWIS desktop conferencing systems with shared spaces, telepointers are used to point to items in spaces shared with other participants. This paper discusses issues in telepointing from several viewpoints. The first part discusses design issues such as the number of pointers and the extent of the shared area. The next part focuses on the relationship between telepointing and the autonomy of each machine. Our tests and discussions show that the more autonomy each machine has, the more telepointing problems arise, and the less WYISWIS is supported. The paper also compares implementation methods. © 1993.
